再看VLC里面的代码流程,是在Pool入口函数里面创建了一个ID3D11Texture2D数组做缓冲区(创建时指定了D3D11_BIND_SHADER_RESOURCE),然后分别创建ID3D11ShaderResourceView绑定到渲染管线。 翻了半天文档,又发现d3d11提供了CopySubresourceRegion这个API用于两种纹理之间进行拷贝。于是迂回作战,尝试把ffmpeg AVFrame里面没有带...

ffmpeg解码后不带绑定属性纹理，通过CopySubresourceRegion拷贝过来，然后套⽤VLC的显⽰流程代码，创建ID3D11ShaderResourceView并进⾏三维渲染。这次，在球体三维模型上顺利显⽰出了视频画⾯。⾃此，⾛了⼀⼤圈弯路，dx9的dxva2和dx11的d3d11va的硬解码和d3d11的三维纹理渲染显⽰都顺利熟悉了⼀遍。...

Having this line vf=lavfi=yadif with hwdec=auto-copy in the mpv.conf works so it is something specific to intel hardware. This line produces smooth playback and cpu usage around 20%. I have no issues with the other pc that use amd or nvidia hardware. This line also works deinterlace=...
Resources are copied automatically to device-accessible memory as needed. Managed resources are backed by system memory and do not need to be recreated when a device is lost. See Managing Resources for more information. Managed resources can be locked. Only the system-memory copy is directly modi...
